The Endura™ ISL6161 from Intersil Corp. is the industry's first dual-rail hot-swap controller targeted primarily for the new PCI Express bus. It allows boards to be safely inserted and removed from live backplanes.
It also controls both 12V and 3.3V power buses, offering programmability and fast-response protection. In addition to PCI Express, the ISL6161 is well suited for general power distribution control and other Hot-Swap and Hot Plug applications. Key features include undervoltage monitoring and “power good” notification, programmable overcurrent detection and fault isolation, programmable current regulation, programmable current limit time to latch off, adjustable turn-on ramp for soft-start, and 1 µ response to a dead short. This dual controller offers customers a high degree of integration that results in savings in board space and balance of materials costs.
